Definitions

  • the present invention relates to a waterproof dummy connector fills a fitting hole for a male connector which is formed in a female connector, to provide a waterproof sealing instead of the male connector.
  • FIG. 2 A cross sectional view of an example related waterproof dummy connector of this type is shown in FIG. 2.
  • a waterproof dummy connector 1 is produced as a two-component assembly, wherein a packing 4 , made of elastic rubber, is fitted around an outer periphery of a fitting convex 3 of a dummy connector main body 2 , made of a hard resin.
  • the related waterproof dummy connector 1 is a two-part assembly, comprising the dummy connector main body 2 , made of hard resin, and the packing 4 , made of elastic rubber, and expenditures for assembly and parts are high, the unit manufacturing cost is excessive.
  • a dummy connector for sealing a fitting hole formed in a female connector, instead of a male connector, comprising:
  • main body and the sealing portion are integrally made of thermoplastic elastomer resin.
  • the main body When the waterproof dummy connector is used, the main body is fitted into and fills the fitting hole in the female connector, and since at this time the integrally formed sealing portion closely engages the inner face of the fitting hole, the hole is sealed.
  • thermoplastic elastomer resin lies midway between those of hard resin and of rubber, both the overall shape and the sealing strength can be maintained. Further, since thermoplastic elastomer resin is employed, the dummy connector main body and the sealing portion can be integrally formed, so that the parts number can be reduced to one.
  • a closing wall is formed at a rear part of the main body for closing the fitting hole.
  • the sealing portion is provided on an outer periphery of the closing wall.
  • a lock arm which is engaged with an engagement member formed inside of the fitting hole is formed on the main body in a front side of the closing wall.
  • the locking arm projects outward from the front face of the closing wall of the dummy connector main body, when the waterproof dummy connector is fitted into the fitting hole it can be surely prevented from falling out.
  • a pair of recessed portions are formed in a rear face of the closing wall, so as to define a gripping wall therebetween.
  • a projection is formed on the lock arm for engaging with the engagement member formed in the fitting hole.
  • the projection has a front slope face and a rear slope face which extend in an inserting direction of the dummy connector.
  • the rear slope face is steeper than the front slope face.
  • FIG. 1A is a rear perspective view of a waterproof connector according to one embodiment of the invention, wherein a waterproof dummy connector is to be fitted into a fitting hole formed in a female connector;
  • FIG. 1B is a front perspective view of the waterproof dummy connector
  • FIG. 1C is a cross-sectional view taken along the line Ic-Ic in FIG. 1B;
  • FIG. 2 is a cross-sectional view of a related waterproof dummy connector.
  • a waterproof dummy connector 10 is used, instead of a male connector, to fill a male connector fitting hole 21 formed in a female connector 20 .
  • the waterproof dummy connector 10 comprises a main body 11 , which is inserted into and fills the fitting hole 21 ; and sealing portions (sealing lips) 12 , which closely fit with an inner face 21 a of the fitting hole 21 .
  • the main body 11 and the sealing portion 12 which are integrally formed of thermoplastic elastomer resin, are large enough to tightly fit in the fitting hole 21 .
  • the sealing portions 12 are provided around the outer face, and a closing wall 13 is formed to fill the mouth of the fitting hole 21 .
  • An integrally formed locking arm 14 projects outward from the front face of the closing wall 13 , and engages with a protrusion (not shown) in the fitting hole 21 .
  • a projection 18 for engaging the protrusion in the fitting hole 21 is formed on the locking arm 14 .
  • a front wall 18 a of the projection 18 has a gentle slope, and while a rear wall 18 b is not vertical, it has a rather steep slope. With this arrangement, because of the gentle slope of the front wall 18 a , only a small amount of force is required to insert the waterproof dummy connector 10 , while to remove the waterproof dummy connector 10 , slightly more force is required because of the steeply sloped rear wall 18 b . Further, two recessed portions 16 and 17 are formed in the rear face of the closing wall 13 with a horizontal gripping wall 15 in between.
  • this waterproof dummy connector 10 When this waterproof dummy connector 10 is employed, the main body 11 is fitted into the fitting hole 21 of a female connector 20 , and the mouth of the fitting hole 21 is filled by the closing wall 13 . Then, since the integrally formed sealing portions 12 closely fit with the inner face 21 a of the fitting hole 21 , the fitting hole 21 is sealed. Further, since the locking arm 14 engages the protrusion formed in the fitting hole 21 , the waterproof dummy connector 10 is securely held and will not fall out. In this state, the entire waterproof dummy connector 10 is accommodated inside the fitting hole 21 , so that there are no protruding portions.
  • the waterproof dummy connector 10 which in size is small enough to be completely accommodated in the fitting hole 21 , can be easily inserted in or removed from the fitting hole 21 .
  • the gripping wall 15 also functions as a rib, and serves to reinforce the strength of the sealing portions 12 , which may be deteriorated by the thin walls at the recessed portions 16 and 17 . Therefore, the gripping wall 15 , by countering a reduction in the strength at the sealing portions 12 , contributes to the maintenance of a secure sealed state for an extended period of time.
  • the relative elasticity of thermoplastic elastomer resin, the material used for the waterproof dummy connector 10 lies midway between those of hard resin and rubber, the overall shape and the sealing strength of the waterproof dummy connector 10 can be maintained. Furthermore, since the dummy connector main body 11 and the sealing portion 12 are integrally formed of using thermoplastic elastomer, the parts number can be reduced to one, so that assembly and part expenditures can be decreased, and accordingly, the unit manufacturing cost can be reduced.
